Question

A proton is projected with a uniform velocity 'v' along the axis of a current carrying solenoid, then ____________.

विकल्प

• the proton will be accelerated along the axis.

• the proton path will be circular about the axis.

• the proton move along helical path.

• the proton will continue to move with velocity 'v' along the axis.

Answer 1

A proton is projected with a uniform velocity 'v' along the axis of a current carrying solenoid, then the proton will continue to move with velocity 'v' along the axis.

Explanation:

The proton is travelling in the same direction as the solenoid's axis. Because the magnetic field inside the solenoid is homogenous, it has no effect on proton velocity.
